The following post summarizes some changes based on patch notes for Korean live servers. American server is currently at v22.80.01 after nearly 4 months of nothing. See Patch Notes page for earlier versions.

In my opinion, the new Enchantment Tranquilizers are still too expensive. Constellation Weapon (AR33) uses Veteran Chip, while Elite Le Noir (DR32) uses Lv.100 Chip. Neither Veteran nor Lv.100 Chip is worth 540,000 Vis... Might as well just throw more chips at the item without using tranquilizer at all. The same with the ones in Feso.

This is the typical problem with the changes by IMC. They changed a system (e.g. Enchantment Separation) or added a new item, then set the cost so high that the item or system is not even worth using... Otherwise, they added a new raid mission or quest, but the rewards are so bad or drop rate so low that it is barely worth the time. (They even changed the game client files so they can hide the drop rates from players...) All these just keep making their changes redundant. The root of the problem is their design philosophy and the stingy-mindedness of the developers...
